The nurse is assessing a client diagnosed with appendicitis. Which of the following signs or symptoms should the nurse expect to find ？（）
A．Rigid abdomen, Levine's sign, pain relief leaning forward.
B．Rebound tenderness, McBurney's sign, low-grade fever.
C．Right lower quadrant pain, Chvostek's sign, muscle guarding.
D．Periumbilical pain, Trousseau's sign, pain relief with pressure.
参考答案：B
解析：
Rebound tenderness, McBurney's sign (pain midway between umbilicus and right iliac crest), and a low-grade fever are all signs of appendicitis. Other clinical findings include a rigid abdomen, a preference to lie still with right leg flexed, right lower quadrant pain, muscle guarding, periumbilical pain, anorexia, nausea, and vomiting. The other findings aren't signs of appendicitis.
